Rosen said Delgado was named as a defendant for "intentionally interfering with [DeMentri's] contractual relationship with NBC." He would not elaborate.
DeMentri was fired in August. The reason was not disclosed.
Delgado's attorney, Eric Weitz, said yesterday, "We are unaware of any facts that support Mr. DeMentri's and Mr. Rosen's allegations."
The state Human Relations Commission confirmed that the commission was investigating a sex-discrimination claim against the station by the Frankford-raised DeMentri, 44. The complaint contends that the station retaliated against DeMentri because he complained about the alleged discrimination.
DeMentri, who worked at NBC10 for five years, anchored its affiliated MYPHL newscast on Channel 17 with Delgado from December 2005 through September 2006. Delgado joined the station in January 2005.
A station source said Delgado told management in June that a hair dryer and other personal items had been moved from her desk drawer to a spot under her desk at the station in Bala Cynwyd.
On July 3, an NBC security official told Lower Merion police that "criminal mischief" had been done to Delgado's car, according to a police report obtained by The Inquirer. NBC has declined comment.
DeMentri, 44, was listed as a suspect in the complaint, which was investigated July 8 and closed when Delgado refused to cooperate with police. The report did not specify the damage to the Lexus.
DeMentri and his attorney, Rosen, have declined to discuss the case publicly.
